javascript - 按钮开关盒

Question

我似乎无法让它在 jquery 中工作。我使用此代码作为必须定义每个按钮的替代方法，但这不起作用:/

此外，我想知道我是否/如何对每个案例使用多个语句。谢谢:)

您需要在 switch 语句中的each case 之后添加一个break。更新了 JSFiddle here .

来自 Wikipedia :

break; is optional; however, it is usually needed, since otherwise code execution will continue to the body of the next case block.

Add a break statement to the end of the last case as a precautionary measure, in case additional cases are added later.

更新的 Javascript:

 $("input[type='button']").click(function() {
   switch(this.id) {
     case 'buttonone': $("#content").html("Content changed"); break; //notice BREAK
     case 'buttontwo': $("#content").html("Content changed again"); break;
   }
 });
